The sum of the interior angles of a polygon is 3600°. How many sides does the polygon have? How do you know

The factored form of

Solution:

From question, given that

To factorize the given expression, follow the below steps:

---- eqn 1              

Taking 4 as a common term in equation 1, we get

“4x” can be rewritten as –6x+2x. Now the above equation becomes,

By taking 2x as common from , the above equation becomes,

Hence the factor of
